Clinical significance

It is considered an insignificant artery that is dissected during hysterectomies. It can be the source of hemoperitoneum,^[8] but only rarely does it pose a hemodynamic risk to the patient if severed and it is easily cauterized or sutured to prevent bleeding.^{[citation needed]}
